They made them in 42mm for about 9 years since 2011 I believe ....and only 745 were made in total between aluminum and titanium in 42mm.
They made only 316 OCTA Sport watches in 42mm , with aluminum case as well as aluminum caliber, before they switched to Titanium. Of those 316, FP also made 100 in *Black* aluminum and of those 100, one stayed with FP in Geneva and 99 were sold.
Therefore only 216 Octa Sport 42mm watches were made with *bright aluminum case* and aluminum movement. However the breakdown between bracelet watches and those watches on the rubber strap is unknown between those 216.
Nevertheless, a very cool and a rare watch. And I would be lying if I didn't say that I'm also intrigued to add a bright aluminum FP cased watch with aluminum caliber to my collection.
